Bad bios checksum

post #1 of 6
Thread Starter 
Hey guys, it's been a while since I've last posted on OCN. Recently I've ran into a problem with my last build in 2010, it has ran strong until the last few weeks. One night I turned my PC off and the next morning while turning it back on, I get a black screen saying I have a "Bad bios checksum" it tells me not to put anything into the cd drive or a USB. It also keeps cycling "checking cd-rom" and "checking for floppy". I don't have a floppy drive nor do i have a bootable CD I can use. I researched on the internet for a little bit and it seems like its only ASUS boards that get this error all the time and all I get is people telling me to replace the little cr2032 disk battery, I've done that twice with no changes in the bootup. Also I've booted up with just the bare minimum, hoping that it was something with the hardware but still nothing. Any help with the situation would be very much appreciated! thumb.gif My specs are as follows:

-Asus Sabertooth X58 LGA 1366
-Intel i7-950
-Kingston HyperX 6gb
-WD Black 1tb hdd
-OCZ Vertex 2 40gb sdd
-OCZ vertex 2 120gb sdd
-Corsair HX1000w PSU
-EVGA GTX 465

Trying not to buy another board, cause they are all over $300 plus and also I can't post in the trade section here.

Did you try clearing the cmos? Here is a link of your manual showing how to do it. LINK Its on page 2-22 Follow the instructions to erase rtc ram

Let me know what happens after doing that.

Bump. I'm lost. I tried downloading the most recent bios to a usb drive and when I put it in, it kept searching for the file and never did anything.

when you replaced the battery and reset the CMOS did you get the option to hit F1 to make changes? also, it is saying don't put a cd in if you are trying to recover from a USB port/device. So you can use a disk if your not trying to do something thru USB. Might want to try throwing a Win disc in there and see what happens. the bios flash might be your best bet atm though

Yeah bios is the next step I would take. Did you follow the instructions on msi website? http://us.msi.com/service/biosupdate/

You have to make sure the bios is an exact match .
Download the zip file unzip it and put it on the usb.
Make sure its a bootable usb drive this one is important and most likely your issue. You need to make it a bootable dos usb drive.
When you do that it will boot to dos prompt then enter what the website shows to enter


Just remember updating your bios can brick your motherboard if not correctly or with the wrong file. I have done bios updates with no issues but make sure you have patience doing it.
